DUMPING-CAR.

v SPECIFICATION forming part of Letters Patent 110,254,138, dated February 28, 1882.

- Application nien December 27, 1881. (No model.)

To all whom it may concern:

Be it known that I, FRANK P. J or'rNsoN, of Waltham', in theveounty of Middlesex and State of Massachusetts, have invented a new and usefuiIm provenient in Devices for Dumpin gRaiiroad Cars or other Similar Vehicles for the '.llransportation'o'f Gravel,Coal, 81e., which invention I'will describe asfollows, reference being had to the accompanying drawings, which form` a part ot' this specification, like letters iu-- dicating like parts in lthe different figures thereof'.

Figure l of the drawings shows in perspective an ordinary gravelcar with my device seen as applied in the manner that I consider the best when the ear is provided with iron corner-posts. This figure shows my device upon'v three corners of the car, though all four of the corners areequipped alikein practice. Fig. 2illustrates the appliance in perspective, as seen in Fig. 1, but detached from the car,"so that all its parts maybe shown fully and indetail. Fig. 3 isa view in perspective,'showin'g lthe device detached from the car, and illustrating the best manner, in my opinion, of attaching my appliance to wooden cori1er1'iosts.

Fig. 4 is a view in perspective of the adj uslt'able detachable lifting or dumping lever',jtl`ie application and operation of which is il'lltistrated in Fig. 1.

My invention consists in what may be termed a ixed segment-gear 7 attached to each of the four corner-posts of a gravel-car or othersimil-ar vehicle, or preferably, for strength, should be cast with the corner-post when said post is of iron, the segment-gear being preferably of iron, as the following description will render obvious; but when the corner-posts are of wood said gear should preferably beinserted in the post, so that the face of the body of the gear shall be ush with the face ofthe corner# post, and the gear bolted or otherwise attached to said post in any suitable manner, the post to be mortised for the admission of the gear; but the gear may be attached to without being inserted in the corner-post. A pin is inserted in said segment-gear by means of an ordinary thread, as shown in the drawings, the inner end of said pin being upset in order to hold it in place 5 or the pin may be inserted and held in place by any suitable and well-known means. Said pin is provided with an annular lip or Bange to prevent the liftinglever from slipping off thereof. The lifting-lever is so shaped that it can be passed over said tlan ged pinand then readily held thereon, the form of construetion of said lever also admitting of placing the same between and bearing it against the eogs of the segment-gear, said lever being readily placedin said gear at any angle rendered necessary by the height of the operator, thel position of the body of the car, or by the relative conti guration ot' the ground upon which the operator is to stand.

Owing tothe necessity of removing the extended ends of the side sills of the car in order to secure the free movement of the lever required, i supply the strength taken from said sidesills by the removal ot' said ends byadoptingmeans in themselves not novel, but new in combination with this device, which Y means( will be hereinafter fully set'forth.

` The following is a full, clear, and exact de scription of the construction of my device, of

vits application to a dump-car, and of its operation.

Each of the four corners E of the car A is provided with the fixed segment-gear B, and arranged upon and forming a part of said segment-gear are the voogs b, as shown. vmore common mode of construction at present iis to make the corner-posts of' gravel-cars of iron, Figs. l and 2 of the drawings show my {invention applied to iron corner-posts; and though the segment-gear may be bolted or otherwise attached to said iron corner-post, I believe it to be better to cast both the segment-A ;gear B and the post E together to secure greater strength.

As'the An examination of an ordinary gravel-car shows that the two side sills, H, are carried a little beyond the corner of the car, and that in the case of iron corner-posts said posts are usually cast so as to extend out upon and to the end of said extension of said sill, for the purposeof strengthening the corner of the car. As is obvious, said extensions at each end of each of the two side sills, H, must be cut off in order to give proper and sufficient room for the operation of the lever D 5 and in order to make good the loss of strength occasioned by the removal ofthe ends of said sills H,I carry the iron plate Jfartheralongin the sill H than is usual, the use of said plate J being customary; but it is not usually carried as t'ar into the sill H as is shown in Figs. 1 and 2. The plate J is so placed in the sill as that the surfaces of the sill and of the plates shall be Bush with each other, and then held in its place in the sill by the boltsjor their equivalents. The piece of iron J is also carried into the sill, as shown in Figs. 1 and 2, for the purpose of lending increased strength; but for those pieces or plates J and J I claim no novelty in themselves, but only in combination with this particular construction of my device-that is to say, when the invention is applied to iron cornerposts. When said corner-posts are of iron I believe the better mode of construction to be by casting said post E, the segment-gear B, the cogs b, and the two plates J and J all to` gether, as shown in Figs. l and 2, for though the segment-gear B may of course be bolted or in some other ot' the well-known ways attached tothe corner-post, it is obvious that the mode of casting all in one piece gives greater strength. The pin G is provided with the lipA or ilange g, to prevent the lever from sli ppin g' off therefrom, and is inserted in the segmentgear B, either by means of the thread g', as shown in Figs. 2 and 3, and upset at its inner end for the purpose of holding it in place, or it may be inserted in any suitable manner.

The cogs b may ot' course be attached to the body of the segment-gear B5 but in order to insure requisite strength they should be cast asa part of said gear, as before stated.

Fig. 4 shows the adj ustable detachable lever,

the entire lever taken together being desig nated D. In Fig. 1 is seen said lever adjusted upon the pin G, and in the hands ofthe oper-y ator, ready for work. The part C of the lever D should be of iron, and preferably carried over and attached to the handle G by means ot' the bolts d, but may be attached thereto in any other equivalent and suitable manner.

The handle C may be ot' wood, or of any suitable material, or the two parts C and fC may be madein one piece, of iron or any'suiciently strong material. The part C is larger at the end next to the handle'C, so that it may be passed over the lip g of the pin G in adj usting, after which the lever is drawn so as to bring the small end thereof to a bearing upon the periphery ot the pin G, as illustrated in Fig. 1. The lever is so made that the double arms d' will tit between and bear against the cogs b, as illustrated in Fig. 1. The inside surfaces of the double arms d ought preferably to be made convex at the smaller end of said double part, so that the lever may work readily and freely upon the pin G.

Fig. 3 shows my device as applied to a wooden corner-post, and attached thereto preferably by the bolts b'; butit may be attached in any other suitable manner. The sills H must be cut oft' at their ends for the same rea- Vson as before stated, and the usual way ot' building wooden-posted cars being to insert the corner-post E in the sill H, as shown in Fig. 3, I, in order to make good thevloss of strength occasioned by the removal of the ends of said sills, (which ends are ordinarily connected with wooden cornerposts by an iron rod or brace for strength,) attach the piece ot' angleiron h to the sill and lto the post by means of the bolts h or equivalent means, or by the use of any equivalent of the angleiron, to insure the requisite strength to the corner ofthe car; but I make no claim to said angle-iron as used in itself, but only in combination with this construction and application ot' my device.

In viewl of the'very clear illustration ofthe operation ot' this device furnished'by Fig. l ot' the drawings, it seems hardly necessary to e11- ter into any extensive description ot' its practical working. I calculate that one man with a lever, D, at each ot' two opposite or diagonal corners of a car can readily dump a modern'- built loaded dump-car, while three or four times this number of men is required to dump a'loatlcd car by a direct lift.

Having fully described my invention and the manner of carrying the same into ef'ect, what I claim as new, and desire to secure by'Letters Patent, is-

In a dumping device, the segment-gear'B, with cogs vb, the corner-post E, with elongated strengthening-plate J, and strengthening-plate J inserted in and attached to the sill H, the pin G, with lip g', and the adjustable detachable lever D, constructed and arranged substantially as described and shown, and for the'purpose setforth.
